Description

  The present invention relates to a training apparatus for external and internal eye muscles.

  As an eye muscle training device, it automatically reciprocates by an electric motor on the upper surface of a guide bar that swings vertically like a seesaw at the upper portion of a fulcrum that rotates reversibly within a range of 90 ° with respect to the axis of the column. There is a device that attaches an index and follows the moving index with a line of sight. Then, instead of the moving index, a foldable three-division guide bar automatically turns on and off sequentially, a small lamp with LEDs etc. By aligning multiple light sources at regular intervals and following the small lamps that are lit, the function is almost the same as that of the moving eye muscle training device. At the same time, the guide bar is folded to minimize the occupied space. A device has been devised.

  However, in both cases, the disadvantage is that the former is troublesome in securing a place for a long guide bar, and the latter cannot create a situation in which the viewpoint gradually changes with distance in the content of perspective training. .

  On the other hand, the instantaneous switching function between the near and near points by the program that can be moved by the former and the program that can be done by the latter and the structure that the guide bar can be folded are advantages, and if one device that combines these advantages can be realized, It can be the most desirable training device.

  The problem to be solved is that a desirable function of the apparatus is a combination of a movement indicator method and a method of instantaneously switching blinking of a small lamp between two near and far points as described in paragraph (0004), and a guide. The bar is foldable so that the occupied space during storage can be minimized, but when a movement index is attached, the handling of strings connected before and after the slider with the index is a problem. The string is connected from the two reels reversibly rotated in the same direction by a DC motor to the front and rear of the slider via pulleys at both ends of the guide bar, and the index can be moved by being always pulled by either direction according to the rotation. However, if the guide bar is simply divided into three parts so that both outer guide bars can be folded, the string will loosen and fall off the pulley at the tip, and when the guide bar is restored to a straight line again, The problem is that the reciprocal function cannot be maintained and cannot be used.

  In order to solve the above-mentioned problem, the present invention provides a string that loosens when the guide bar is folded by mounting one hook roller of an appropriate diameter at an appropriate position below the rotating shaft of both guide bars to be folded. Is maintained and tension is maintained to prevent the string from falling off the pulley, and it can be folded and stored even in a training device that follows the movement index. By the way, although the approximate amount of change in elongation at the time of folding by using this hook roller is about several millimeters on one side, it can be absorbed within the range of elongation that gives tension during use due to the elasticity of the string. .

  By adopting the device of the present invention that prevents the string from loosening and falling off the pulley when the guide bar is folded, the guide bar can be folded and stored even in a training apparatus that follows the movement index. If you add the function of the instantaneous viewpoint switching method that repeatedly turns on and off the small lamp between two points, you can produce a combined training device that has the advantages of both training devices and overcomes the drawbacks at the same time. It becomes.

  How the hook roller entangles and prevents loosening when folding the guide bar, the relationship with the string, roller, pulley, hook roller, reel, etc. by changing the folding angle of the guide bar every 30 ° in Fig. 1 Indicates. Since the arrangement of the string attached to the guide bar is almost symmetrical, the slider for attaching the index is placed in the center of the apparatus, and the “string end point” connecting the slider and the string does not move. The state of the half string is indicated by a bold line.

By making the guide bar foldable, it is important not only to loosen the string, but also to ensure that the running surface on which the slider travels has a uniform continuity. Since a slight step at the split part is unavoidable, even if there is a slight step, the part where the running surfaces of the split part face each other is slightly scraped off on both running surfaces. In order to prevent downward force from being applied to the slider via the string, the pulley center level and diameter should be adjusted so that the level of the string hook of the pulley on both ends is not lower than the level of the slider string end point position. decide. Also, since the horizontality of the guide bars on both sides varies depending on the backlash of the gears and the manufacturing accuracy, the rear connecting plate (16) and the left and right guide bars (13, 14) after the adjustment of the running surface level. A knock pin (63) is inserted in between to suppress the fluctuation (see FIGS. 5 and 9).

   As an embodiment, the appearance and details are shown in FIGS.

The guide bar is divided into left, center and right guide bars (13, 12, 14), front / rear connecting plates (15, 16), slider (70), movement index (71), string (60), front Rear reel (25, 26), pulley (37), bush (38), front / rear center cover (17, 18), left / right cover (19, 20), cushion (72, 73), shaft (22 24, 46), gears (21, 23, 32, 33, 34), ball bearings (27, 28, 39), rollers (29, 56), hook rollers (36), knock pins (63), reel covers ( 65), knob (64), plunger (49), and other fastening parts. The central guide bar (12) is composed of one piece, and the left guide bar and the right guide bar are each composed of five pieces (reference numerals 131 to 135, 141 to 145). (See FIGS. 7 to 16)

  As shown in FIG. 7, the assembly procedure of the guide bar portion is as follows. First, the ball bearing (27) is attached to the front side of the central guide bar (12), the shaft (22) is inserted, and the rear side ball bearing ( 27) and install the gear (21). A screw (62) is attached to the axial stop of the gear (21). Next, with the front reel (25) and the rear reel (26) placed inside the central guide bar (12), the shaft (24) is passed through and the ball bearing (28 from the front side of the central guide bar (12) is passed. ), Install the truss screw (42), washer (52), and spring washer (54) at the end, install the ball bearing (28) and gear (23) from the rear side, and engage the gear (21) normally. Confirm that this is the case and install the washer (75), spring washer (53) and nut (47). At this time, one end of the string (60) cut into the reels (25, 26) including the adjustment length to the required length before mounting is fixed with an oval sleeve (59) and embedded in a predetermined position (see FIG. 8). ) The other end is rounded to the extent that it does not hinder and secured with tape or the like. A fishing line with a diameter of about 0.52 mm is recommended for the string. The winding around the reel and the connection with the slider are performed at the final stage.

As shown in FIG. 9, the rear connecting plate (16) is laid horizontally with the back side down, and the gears (34) are placed at four predetermined positions, and the central guide bar (12 ) Is attached to the shaft hole for the gear (34) while passing the motor-side hub portion of the gear (21) through the center shaft hole of the rear connection plate (16), and the rear connection plate ( 16).

As shown in the cross-section EE of FIG. 10, the spacer (31) is passed through the left rear bar (135) and the gear (32), and the gear (32) is in a position where the spacer (31) moves lightly. Then, fix the gear (32) with a flat head screw (61). The spacer (31) is protruded about 3 mm from the end face of the gear (32). Incidentally, the gear (32) is notched so as not to interfere with the reamer hole machining of the knock pin (63), and the gear bar is arranged for the right guide bar (14) in order to make the guide bar straight when in use. Since it is uniquely determined together with the gear (33), a phase mark or the like is provided in advance to facilitate installation at the correct position. After fixing the gear (32), the left middle third bar (134), the left middle second bar (133) with the roller (29) inserted into the bifurcated portion, and the left middle first bar are assembled through the spacer (31) in this order. At this time, the electric wiring with the lamp (92) mounting seat and the microswitch (94), which has been manufactured in a full-size mold in advance, is mounted at a predetermined position of the first middle bar (132), As shown partially in FIG. 11, before passing the wiring to the central guide bar (12) side, it is wound from the lower side around the boss of the spacer (31) insertion portion in order to absorb the influence of expansion and contraction during folding. Then, the wires are routed, passed through the groove of the central guide bar (12), and taken out via the groove on the central shaft. Since the wiring of the right guide bar (14) and the DC motor (91) is also gathered in one connector at the tip of the wiring, handle with care. Subsequently, the spacer (31) is passed through the left front bar (131), and the fastening parts (35, 48, 52) are also attached to the middle portion of the guide bar and temporarily fixed as shown in the cross section CC of FIG. The plunger (49) is attached to the side surface of the front and rear bars (131, 135) as shown in the cross-section DD of FIG. As shown in the cross-section EE, the locking roller (36) for preventing the string (60) from loosening is placed between the left middle first bar (132) and the left middle third bar (134), and the shaft (46) is moved forward. Insert from the hole on the part bar (131) side and install. A pulling tap is cut off on the shaft (46) just in case.

The right guide bar (14) is similarly assembled. As shown in FIG. 9, the spacer (31) protruding from the end face of the gear (32, 33) of the assembled left / right guide bar (13, 14) is inserted into the mounting hole on the rear connecting plate (16) side, Check that the guide bar can open and close smoothly at an equal angle. By the way, when the gears (32, 33) and the gear (34) are brought together, it is performed at the meshing position where the guide bar is in a straight line. If there is a meshing phase mark on each gear, it will be a guide for angle matching. The wiring drawn out through the axial groove of the central guide bar (12) is put out through the hole of the front connection plate (15). Subsequently, the shaft of the central guide bar (12) is passed through, and the front end of the spacer (31) is also passed through a predetermined position. As shown in the cross section EE, the fastening screw (30), the washer (75), Install the nut (47). The spacer (31) is inserted in order to prevent the guide bar and the connecting plate from coming into close contact with each other by tightening the screw, and an excessive frictional force is applied, and a spacer having a controlled length is used.

With reference to the travel indicator travel surface of the middle guide bar (12), the travel surfaces of the middle second bars (133, 143) of the left and right guide bars (13, 14) are aligned, and the fastening parts ( 35, 48, 52) is tightened. Incidentally, the hole for the fastening part Trusco screw (35) of the middle second bar (133, 143) is an oblong hole in the vertical direction so that the level can be adjusted. Check that the left and right guide bars (13, 14) can be opened and closed smoothly at the same angle after the final tightening.

As shown in FIG. 12, bushes (38) are attached to the pulley attachment portions on both ends of the left and right middle No. 1 bars (132, 142), and ball bearings (39) are incorporated into the pulley (37).

  Fully tighten the left and right guide bars (13, 14) with fastening parts (35, 48, 52) in order to reduce the wobbling of the bar due to looseness of the synchronous rotation gears (32, 33, 34). Thereafter, a reaming hole for a knock pin is formed between the rear connecting plate (16) and the left and right rear bars (135, 145) at the position shown in FIG. At the time of training, a knock pin (63) is attached at this position, removed after completion, and stored in a storage box (76) attached at the final stage so as not to lose it. On the back side of the left and right rear bars (135, 145), a knob (64) that can be used when changing the inclination of the guide bar is attached at a predetermined position (see FIG. 3). If the hand gripping the grip (68) is raised slightly upward, it can be touched, and the outside of the knob will rotate freely.

The plunger (49) is attached to the rear surface of the front bearing (8) at the position shown in FIGS. 7 and 16, and the electrical wiring from the central guide bar (12) is coaxially passed through the central hole, and the rear bearing (9 ) Pass the shaft of the rear connecting plate (16). By the way, the plunger (49) attached to the back side of the front bearing (8) corresponds to the positioning hole for every 15 ° of the swing angle of the guide bar provided on the front side of the front connecting plate (15). Hold the peristaltic posture. Further, on the front plate (15) side, numerical values and lines indicating the swing angle are engraved in accordance with the position of the side of the upper surface of the front bearing (8) so that the swing angle can be seen at a glance (see FIG. 16). Each bearing is fixed to the fulcrum base (5) with a pan-head screw (45) and a washer (75).

After the DC motor (91) is mounted on the motor mounting seat (66) with the Trusco screw (42), the output shaft of the DC motor is inserted into the rear bearing (9) in accordance with the end face hole of the gear (21). The seat (66) is fixed to the back surface of the bearing (9) with a Trusco screw (42) (see FIGS. 5 and 7).

The front bearing side wiring and the rear bearing side wiring (motor wiring) pass through the groove of the bearing and the fulcrum base, through the lower part of the fulcrum base, through the slit of the screw part (4), and the hole of the lock nut (6) Then, the connector at the end of the wiring is taken out from the notch portion for taking out the wiring on the lower surface of the support via the inside of the support (2). Before inserting the wiring, insert the lock nut (7) and the rotating strut (3) in this order until the lower surface of the rotating strut (3) hits the collar surface of the upper end of the strut (2). Then, through the notch hole for 90 ° rotation of the rotating support post (3), it is attached to the screw hole of the support post (2) with a decorative nut (57) and washer (52) with a Trusco screw (43) (see FIG. 7). . After the end connector of the wiring is taken out from a predetermined position below the support post (2), the support post (2) is installed in accordance with the seat of the leg (1), and is fixed with a screw (74) (see FIG. 2).

The control box mounting seat (69) is attached to the leg (1) with a Trusco screw (42), and similarly the control box (90) is attached with a Trusco screw (42). The wiring connector from the column side is connected to the wiring connector of the control box (90), and the wiring cover (96, 97) is attached to the fulcrum base and the wiring cover (98) is attached to the rear part of the control box ( FIG. 2 ) . FIG. 4 ).

Next, the string (60) is attached to the slider (70). Extend the guide bar in a straight line and attach the knock pin (63). The tape etc. which fixed the string to each reel are removed and opened, and adjustment is performed from the rear reel (26) side.

Turn the rear reel (26) from the front and rotate it about 7 turns counterclockwise to wind the string (60) and hold it with special tools so that the reel does not rotate even if you release your hand. Pass the end of the hook through the hook roller (36) for preventing loosening when it is folded, hook it on the pulley (37) of the right guide bar (14), and turn it upward to move the slider (70) to the center guide bar (12). Insert into the end mounting hole of the slider through the hole of the oval sleeve (59) at the center position, pass the string coming out of the hole through the oval sleeve again, and fold it back to the oval sleeve three times and crimp the oval sleeve Cut an unnecessary tip (see FIG. 14). The cut length is such that the string does not sag at the center of the slider.

Subsequently, the string of the front reel (25) is attached. The rear of the front reel (25) has three equally-spaced projections that can be stopped on the rear reel (26) at a pitch of 20 ° so that it does not interfere with the rear reel. Move the reel to, turn it about 7 turns clockwise, wind the string (60), hold it with a special tool so that the reel will not turn even if you release your hand, and prevent the loosening roller (36) After passing through the inside of the left guide bar (13) on the pulley (37) and turning upward to cut the excess string in the same manner as the string on the rear reel (26), the front reel (25 ) Adjust the strength of the tension by turning the dedicated tool to hold. When stopping the rotation, the front reel (25) is moved rearward to place the convex portion on the back into the hole of the rear reel (26), the mounting position of the tool is changed, and the front reel (25 ) Is moved forward and turned repeatedly. After the adjustment, the front reel (25) is moved rearward, all the rotation stoppers are removed, and the C-shaped tab (50) is attached (see FIG. 7). After the string adjustment is completed, it is confirmed whether the string (60) on the lower surface of the guide bar is correctly guided to each reel according to the arrangement of the rollers (56), and if necessary, is corrected to the correct position (see FIG. 13).

Set the movement index (71) on the slider, supply DC power to the control box (90), turn on the start switch, move the slider (70), and confirm that the microswitch (94, 95) operates normally. Check. A dummy micro switch (no wiring required) is attached on the opposite side so that the slider does not move laterally due to the reaction force of the leaf spring of the micro switch. If there is a roll at this point, adjust the position of the related micro switch. . (In FIG. 14, a dummy micro switch using the same leaf spring is used to prevent lateral movement, but other methods such as limiting the width of the slider travel path instead of the dummy switch are possible.)

At a predetermined position on the upper surface of the guide bar, the rear center cover (18), the left cover (19), and the right cover (20) are attached with a Saraco screw (58). The front center cover (17) is attached to a seat protruding from the front connection plate (15). A nose pad (10) is attached to the front surface of the front bearing, a cushion (72) is attached to the end of the left guide bar (13), and a cushion (73) serving as a nose pad is attached to the end of the right guide bar (14). A lamp (92) is mounted on the left cover, and a lamp (93) is mounted on the right cover (20) (see FIG. 15. The shape of the electric wiring portion in the drawing is for the right guide bar). A reel cover (65) is attached to the lower surface of the center cover (12) with a pan-head screw (44) and a washer (51).

An electric motor cover (67) is attached to the back of the bearing (9) with a pan-head screw (44) and a washer (51). A storage box (76) is attached to the back of the fulcrum stand (5) with a Trusco screw (42). This completes the assembly.

It supplements about how to use the device. The DC power supply is supplied and the start switch (911) is pressed to start, and the movement index moves to the left. The left micro switch (94) is operated to turn it back and play a single note twice. Moves to the right and plays a single note when folded by the right microswitch (95). The lamps (92, 93) are lit in blue according to the sound of each turn. At 5 reciprocations and 10 reciprocations, 3 consecutive notes are played, and at 15 reciprocations, 3 consecutive sounds are repeated 3 times, and at the same time, the counter is incremented by 1. The blue lighting of the lamp is also linked to the sound of the performance. Each posture based on the inclination and rotation of the guide bar is referred to as a mode, but the training content is based on the implementation of 15 reciprocations (increment of 1 count) in each mode for the extraocular muscles. This is not the case for the perspective mode for the internal muscle. The movement index is color-coded in red, yellow, green, white, etc., and the Landolt ring and characters are displayed on the front and left and right sides of each band, and if it can be read at the far-end position in the perspective mode, it will be somewhat equivalent to visual acuity The calculated size corresponding to 1 to 3 types of visual acuity is displayed. When you want to train with only the ramps (92, 93) without using the movement index (71), switch by pressing the 2-point switch (912) on the control box, and the one with the slower ramp switching speed automatically. Selected. Press again to select the faster switching speed. From the 3rd time onwards, it will be repeated. The object to be displayed on the lamp surface is the same as the movement index. There are two mounting positions for the lamps (92, 93) on the left guide bar (13) side, which are far and near, and on the right guide bar (14) side, two positions adjacent to the cushion (73). it can. ( However, the near-point side of the left guide bar (13) cannot be used when the movement index (71) is used.) The lamp is normally lit in green, and is lit in blue at 5 round trips, 10 round trips, and 15 round trips. To do. The counter is also incremented by 15 round trips and added to the movement index count for display. To return to the movement index mode, the changeover switch (913) is pressed. The reversing switch (914) functions during operation of the movement index and can be reversed at an arbitrary position.

  Example 2 is an eye muscle training device configured to use a flexible joint (80) partially shown in the upper right of the drawing instead of the gear (21) shown in FIG. 7 in the rotation transmission part of the DC motor. . By using a flexible joint with a large allowable eccentricity and declination of the input / output shaft, the manufacturing accuracy of the rotating body on the driven side and the member that supports the rotating body is reduced, and the cost can be reduced.

The structural difference is that the gear (21) and the shaft (22) are replaced with the gear (81) and the shaft (82), and a flexible joint (80) is added between the DC motor and the gear (21) and the shaft (22) are bent first during assembly. The hub on the driven side of the joint (80) is mounted on the shaft (82) and fixed with the screw (83), and is assembled in the same manner as in Example 1. In the DC motor mounting procedure, the hub is mounted on the motor mounting seat (66). In the state where the driving side hub is attached to the output shaft of the DC motor (91) and fixed with the screw (83), and the concave portion at one end of the spacer arranged at the intermediate portion of the flexible joint is fitted to the convex portion of the driving side hub, The other structure is the same as that of the first embodiment only by attaching the motor mounting seat (66) to the rear bearing (9) while aligning the concave portion on the opposite side with the convex portion of the hub on the driven side. In the drawing of the flexible joint (80) in FIG. 7, it is difficult to express, so it is shown as one part.
